bwelch has asked for the
wisdom of the Perl Monks concerning the following question:

Fellow monks,
In a function that reads several million rows from a database, I'm finding it is taking a very long time to complete. I recently added use warnings; to the script and am now seeing this message many times in the log:

"Use of uninitialized value in concatenation (.) or string at cf.pl line xxx"

I'm not seeing what is not initialized here. Do you?

Since this is taking a long time to complete, could you recommend any optimizations?
thanks,
Bryan
